[Arthroscopic repair of avulsion fracture of the posterior cruciate ligament at the tibial insertion].

Avulsion fracture of the tibial insertion of the posterior cruciate ligament (PCL) is a rare condition. Until recently, bony avulsion fractures of the PCL have been repaired with open reduction and internal fixation. Posterior approach commonly used for open repair is rather extensive, yet it does not allow for detection and management of associated intraarticular injuries of the knee. We report a case of avulsion fracture of the tibial attachment of the PCL managed by arthroscopic reduction and fixation. A large bony fragment that extended into the posterior part of the lateral tibial plateau allowed for reduction and retrograde fixation through anterior portals only.
